Description

Dahua's PFM800-4K is a set of passive signal transmission devices for analog system devices. The product enables the transmission of high-definition video signals (AHD, HDCVI, HDTVI, CVBS) via twisted-pair cable. The device matches the impedance of the coaxial cable to the impedance of the balanced cable, enabling signal transmission up to 250m in 4Mpx/5Mpx resolution or up to 200m in 4K (in the case of the CVI system). The anti-interference protection and noise elimination system used in the device give a great sense of security and productivity of communication. The set includes two transformers that are universal and can be used both as a transmitter and a receiver. What's more, all transmitters can be combined into larger groups, thus increasing the visual appeal of the installation.

We present PFM800-4K, the latest real-time transmission technology. This powerful device offers a trouble -free installation without the need for a power supply, making it perfect for any application. Enjoy the excellent anti -capacity, anti -static and anti -anti -anti -nicted properties, as well as compatibility with HDCVI/TVI/AHD/CVBS formats. For greater convenience, the PFM800-4K is equipped with a female BNC connector and connected screw clamps.
